Question
A car travels a distance of 240 km in 4 hours. If it
increases its speed by 20 km/h for the next 3 hours, how much distance will it cover in total?Solution
Initial speed = Distance / Time = 240 / 4 = 60 km/h. New speed = 60 + 20 = 80 km/h. Distance covered in next 3 hours = Speed * Time = 80 * 3 = 240 km. Total distance = 240 + 240 = 480 km. Correct answer: A) 480 km
